Language: implicit nullable E_DEPRECATED omits function name prefix — Zend "f(): Implicitly marking…" (zend_compile.c) #29274

Problem
Under PROFILE≥8.4, implicit nullable parameters (function f(int $x = null)) correctly emit E_DEPRECATED, but the message omits the function-name prefix Zend prints.
Probed 2026-08-09 @ ae8a067be1 vs php:8.4-cli 8.4.24 (PHP_COMPILER_PROFILE=8.4). VM and JIT agree (both wrong). Prior issues (#21390 / #22987 / #23720 / #26083) fixed silence; remaining gap is message shape.
| Repro | Zend 8.4.24 | VM / JIT |
|---|---|---|
function f(int $x = null) {} |
f(): Implicitly marking parameter $x as nullable is deprecated, the explicit nullable type must be used instead |
Implicitly marking parameter $x as nullable is deprecated, the explicit nullable type must be used instead (no f():) |
